WATER-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 767,746, dated August16, 1904.

Application filed April 15, 1904.

'l T0 a/ZZ whom, t may concern:

zen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a new anduseful Improvement in WaterfPuriers, of which the following is aspecification.

My invention relates to the means employed in water-purifying apparatusfor automatically supplying the chemical solution in predeterminedproportion to the water to be treated for softening or purifying thewater, thereby better to adapt it for industrial purposes; and itrelates particularly to an improvement upon the apparatus for thepurpose stated set forth in United States Letters Patent No. 732,357,dated June 30, 1903, to Cass L. Kennicott.

My object is to provide an improved con-l struction of the mechanismactuated by the tilting receptacle to feed to it the predeterminedproportion of the chemical solution from the holder thereof, thereby,particularly with reference to the device of the aforesaid patent, toincrease the capacity of the holder and to simplify its construction andoperation.

In the accompanying drawings, Figure 1 shows my improved apparatus infront elevation with parts represented by dotted lines, and Fig. 2 is asection taken at the line 2 on Fig. 1 and viewed in the direction of thearrow.

A is the tank or holder for the chemical solution, shown of generalcylindrical shape, and it is usually connected for supplying it with achemical-mixing tank (not shown) such as is commonly provided inapparatus of the classk to which my improvement relates. Adjacent to thebase of the holder is journaled on a suitable support c@ to rock on itscenter the tilting receptacle B of the preferred scoop form illustrated,with a central vertical partition I) within it, dividing it intocompartments c and c'. The water to be treated enters the receptacle Bfrom a valved supply-pipe C.

A rope d, chain, or other suitable flexible mediumis fastened at itsends to the opposite ends of the receptacle B, passing therefrom overtwo sets of pulleys e e and e e', journaledon sup- Serial No. 203,324.(No mdel.)

down into the latter between the pulley sets I about a guide-sheave g,journaled in the holder near its base. On the rope (l, within thechemical-solution holder and preferably on each length thereof, asshown, is fiexibly fastened a cup L, the capacity of which should besuitably proportioned to that of each compartment in the tiltingreceptacle to be filled by lowering it from the contents of the holder Aand discharged when raised over the upper edge of the latter into ahopper c', from which a pipe 7c leads downward to the receptacle B.Guides are provided, one foreach cup, in its movements, that shown inFig. 2 comprising a pair of parallel longitudinally-slotted bars Z,fastened in proper position to the inner surface of the wall of theholder to eXtend'vertically therein and beyond its upper edge, overwhich each bar is arched toward the hopper. The cup is hinged at' itslower edge to the rope and has lateral studs confined in the slots ofits guidebars Z, whereby as the filled cup is raised to the position ofthat shown in Fig. 2 and by the full lines in Fig. 1 it is turned toempty its contents into the hopper z'. A shield n is provided foreachcup to extend over it, being supported for that purpose in the tank onthe rope Z therein. This shield tends to prevent, in settlement of thesolution in the tank, the deposit of particles in suspension into thecup, which would unduly increase the strength of its contents, andduring the period that the apparatus is out of operation the shieldprevents such a deposit in the cup as would tend to clog it therewith.As the water to be treated flows into the receptacle B from the pipe Cit fills the compartments of the receptacle alternately, thereby rockingit and discharging into a tank (not shown) for the water undergoingtreatment the one compartment while the other is filling. This rockingmotion of the receptaclel actuates the rope l alternately to lower andraise the cups /L L, whereby the contents of each are introduced intothe respective compartments of the tilting receptacle before they becomefilled with the water to be treated.

The gist of my improvement consists in so connecting with thel tiltingreceptacle the cup or cups as to adapt the latter to be moved verticallyin the chemical-solution tank. This enables me to increase the capacityof the solution-tank over that of the aforesaid patent, since it permitsthe base of the tank to be flat instead of rounded, and the constructionis much simpler and materially cheaper to produce than that of thepatented apparatus, because of the regular form permissible for thesolution-tank, of the omission of the conduits for conducting thesolution to the tilting' receptacle, and of the rock-shaft and linkconnections between the holder and receptacle, while the friction due tothose connections and that of the cups against the sides of the holderis dispensed with, thus enabling the apparatus to run more easily.

While the means shown and described for embodying the aforesaid gist ofmy improvement are thoroughly practicable and desirable, it may beembodied in other forms. Hence I do not limit my invention to theparticular form of its embodiment herein set forth.

What I claim as new, and desire to secure by Letters Patent, is-

1. rlhe combination with a chemical-solution holder of a water-purifyingapparatus, of a tilting receptacle supported to be rocked by the weightof the water to betreated flowing into it, cup raising and loweringmechanism connected with said receptacle to be actuated by its movement,and a cup supported in said holder by said mechanism to be therebyvertically raised bodily above the liquid-level in the holder andlowered therein.
